Former Manchester City and Preston man Nash is in his second spell with the Potters, after re-joining in 2010, and acts as third choice behind Thomas Sorensen and Asmir Begovic.
And manager Tony Pulis has revealed his delight at keeping the experienced shot-stopper with the Staffordshire outfit.
"It is important for us to have three top goalkeepers in the squad at this level and we are as strong in that department as any Premier League club," he told reporters.

"He has done a fantastic job in the time he has been back with us and I have every confidence he will do a great job if he is called upon this season.”
38-year-old Nash has led a nomadic career, starting out with Crystal Palace in 1996 and enjoying spells with Stockport, Wolves, Middlesbrough and Wigan.
He also helped Pulis’ men in gaining their place in the Premier League during an earlier loan spell in 2008, before moving on to Everton.
However, he failed to make a single appearance for the Toffees and returned to the Britannia on a free transfer.
